Short answer
A replica IW323775 is a copy of an IWC watch, not an IWC watch. The number follows IWC's format: the letters IW plus six digits. IWC catalogs checked for this guide do not list IW323775. Treat the number as a seller's label, not a factory reference.
How IWC reference numbers work
IWC writes references as IW followed by six digits, such as IW323902. The first four digits name the model family. The last two name dial, strap, and finish variants inside that family.
The closest published family is the Ingenieur Automatic, built on the IW3239 group. That group uses a 40 mm steel case, caliber 30110, and 120 m water resistance. The digit string 323775 does not match a published variant in that group.
What replica sellers mean by IW323775
Replica sellers reuse IWC-style numbers to signal a target model. A listing titled IW323775 points to an Ingenieur-style three-hand watch, not to a real IWC SKU. Ask the seller for a photo of the caseback engraving. Real IWC casebacks carry the reference and a serial number that IWC service records can match.
Movement and case checks
- Movement: the IW3239 group runs caliber 30110, a modified ETA 2892. Replica builds use Miyota 9015, Seagull ST2130, or ETA 2824 clones. Read the rotor text through the caseback.
- Case: 40 mm diameter on the published Ingenieur Automatic. Measure the case with calipers, not with a photo.
- Water resistance: 120 m on the genuine watch. Pressure-test any replica before contact with water. Many copies fail at 30 m.
- Crystal: sapphire with anti-reflective coating. A mineral glass copy scratches with a steel key.
- Bracelet: integrated lugs on the Ingenieur line. Check that the end links sit flush with no gap over 0.5 mm.
Price bands
Replica listings for this style run about $150 to $400 for standard copies and $500 to $900 for high-grade builds. A steel Ingenieur Automatic from the IW3239 group sells on the secondary market for about $3,000 to $5,000, based on condition, box, and papers. A gap that large is the main reason buyers ask about replicas.
Legal status in the United States
18 U.S.C. 2320 makes trafficking in counterfeit goods a federal crime. U.S. Customs and Border Protection can seize and destroy shipments. Personal use carries less risk than resale, but a seized parcel is still a loss, and the trademark is still infringed.
Checks before you buy
- Ask for the reference number stamped on the caseback, not the listing title.
- Request a movement photo with the rotor in view.
- Compare case diameter and thickness to published specs.
- Ask for a pressure test result in writing.
- Confirm return terms before payment.
Unknowns
No official IWC record for IW323775 was found. If a seller cites an IWC catalog page, ask for the year and page number. If the answer is vague, the number is invented.
